1 This-invention relates to an unreeling device and more particularly toan unreeling devicefor unreeling Wire at a, high rate of speed.

lIn industries, in order to'obtan high production, it is necessary tounreel wire at a veri7 high rate of speed; In my Patent No. 2,362,920 Ihave disclosed an unreeling device for unreeling wire at a high rate ofspeed, wherein the wire is passed between tension rollers. vThis deviceisV suitable for unreeling wire at high rates of speed; but it has atendency to flatten the wire, especiallyif the wire is made from softmaterial. For som'e` purposes a slight iiattening of the wire isnot.objectionable. However, in winding'co'ils, et cetera, where extremeaccuracy is required, a flattening of the wire may be objectionable.

An object of this invention is to provide an reeling device forunreeling wire at a high rate of speed without mutilating the wire.

Another object ofvthis invention is to provide an u nreeling device forunreeling ne wire at a high rate of speed without snarling ,the wirewhen the unreeling operation is abruptly interrupted. Y I

- Other objects and advantagesl resideV in the construction. of parts,the combination thereof and the -modeof` operation, as Ywill become moreapparent from the following description.

-In the drawings,

Figure 1 is a side elevational view of Amy unreeling device.

.Figure 2 is a frontelevational view.

Figure 3 is a 'cross sectional view of the friction drum takensubstantially on the line 3--3 of Figure 2.

Figure 4 is a fragmentary cross sectional view taken substantially onthe line 4-4 of Figure 1.

The device disclosed herein is well adapted l for unreeling ne wire at ahigh rate of speed.

For example, No. 39 wire may be withdrawn at the rate of 8000 feet perminute, more than 90 miles per hour. No. 42 wire, which is much finer,may be withdrawn at the rate of more than 5000 feet per minute,approximately 57 miles f per hour. Furthermore, the withdrawalY of thewire may be abruptly stoppedv without snarling and' without raveling'thewire from the spool. The device for accomplishing these results will nowbe described.

' Referring tothe gdrawings, the base I0 supports a standard I2,'whichmay be a rodY or tubular member. A bracket I4 is adjustably mounted uponthe standard I2 and heldin any s claims. (C1. 242-123) 2 adjustedposition by a suitable set screw4 I6. Thebracket UI4 is provided withYan aperture receiving a;pintle I8, held in position, by a set screw20.k The pintle I8 forms Vthe axle for a pulley 22, provided with anannular groove 24.

Thebottom ofthe annular groove 24 `is lined with feltA 26, or any othersuitable similar material, asforfexample, adhesive tape. The hub 28 ofthe pulley 22 is preferably. provided with friction. surfaces, engagedbyfriction discs or-washers 30and 32, vproviding a braking action uponthe pulley. .The Veffectiveness ofV the braking action ymay be adjustedby adjusting the knurled nut 34 threadedly engaging the reduced end-360f the pintle I8 and holding Ya spring .38 under compression.Y One endof the spring 38'is engaged by the nut 34 vand the opposite end isseated againsta non-rotatably mounted clutch member 40, 'provided withasuitable radially disposed slot, inwhich is seated a pin 42 xedlysecured in a suitable aperture in the reduced portion 38 of the pintleI8. If it is found desirable to increase the braking-action, itis-merely necessary to tighten-the nut 34. In order to reduce thebraking action,jthe nut 34 is loosened.

VThe unreelingdevicel is provided with a pair of'wirefengaginglfrictionpads 50'and 52. The pad' 50, which is folded along theedge'54; isclamped rbetween an extension of a bracket 56 and a clamping member 58held in position by a bolt 60 provided with a wing nut 62. The lower endof the bracket 56 is mounted upon the outer end of the pintle I8 and isheld in position bya spring washer 64 engaging a washer-like key 66seated in a groove in the outer end of the pintle I8. By tightening thewing nut 62, the sides. of the pad 50 are tightened against thevwire.The lower pad 52 is clamped between an' extension 'I8 of the bracket I4and a clamping, member 'I2 held in position by a suitable bolt 1 4provided with an adjustable wing nut 16. As the wire leaves the spool80, which is properly aligned by an upwardly directed pintle 82 mountedin the baser I0, it passes through a tubular member 84 aligned with theaxis of the spool and seated in an extension 88 of the bracket I4. `Thetubular memberr8v4 is tangentially disposed with respect to thewire-engaging surface in the groove 24 o f the kpulley 22. The

' friction pad 52, as may be clearly seen in Figures 1 and 2, is locatedbetween tubular member 84 andy thepulley 22 and aligned with thelongitudinal axis of thevtubular member 84. After leaving the tubularmember 84, the wire passes 3 between the folds of the pad 52 around thepulley 22, the wire engaging the friction material 2B, then up betweenthe folds of the pad 50.

The wire being withdrawn at a very high rate of speed has a tendency toWhip outwardly, especially in the event the Wire is decelerated. Thehoop |00, supported upon a bracket |02 held in adjusted position uponthe standard I2 by a bolt |04 provided with a wing nut |06, is used inlimiting the whipping movement of the wire as it leaves the spool. Inother Words, the hoop counteracts the centrifugal force acting upon thewire. A transverse rod |08, exteding part way across and in spacedrelation from the loop 100, prevents convolutions of the wire fromjumping upwardly, so as to entangle the parts associated with thetensioning of the Wire.

The tension of the wire wrapped around the periphery of the pulley 22may be adjusted by adjusting the wing nuts 62 and 16. The braking effectof the pulley 2-2 may be adjusted by adjust; ing the nut 34. By thisarrangement, the tension of the wire leaving'the spool may be veryaccurately adjusted, so as to obtain the maximum e'ciency. Theseadjustments are critical, in that the wire withdrawn may have a diameterconsiderably less than the diameter of a human hair. The speed of thewire being withdrawn is very high. When it is compared to miles perhour, from 57 to 90 miles per hour, it can readily be seen that thevelocity of the wire is Very great. The device disclosed herein has beenfound to give excellent results in withdrawing wire at extremely highspeeds.

Although the preferred embodiment of the de vice has been described, itwill be understood that within the purview of this invention variouschanges may be made in the form', details, prof portion and arrangementof parts, the combination thereof and mode of operation, which generallystated consist in a device capable of carrying out the objects setforth, as disclosed and defined in the appended claims.
